I don't understand any of this. I'm trying to win a contest. I can be found in clothing, canned goods, stores, libraries, storage bins, and schools. What am I?
Canned goods have
That piece of paper wrapped around it.
Labels on each book for the call number
Storage bin has
Labels to mark what's inside
School kids have labels on their belongings.
My guess is:
Atoms. They are found in everything you mentioned.
